I questioned this briefly when I was told by my doctor that I needed to rest and not do anything physically taxing. I did as she ask, stayed at home did nothing that would stress my mind or body and in general was as easy as possible on my self. As I started to feel better I thought I would just start doing things as I used to one day. That was a serious mistake it was like I returned right back to the day after my accident. The stress I placed on myself was more than I could deal with. There is good advice in the rest till your brain has had a chance to recover. Which is what I am doing now. When it has and my doctor has told me I am god to go I will start working on building my body back up to normal.
